Explanation
PASSAGE
The paradigm shift _____ established methodological approaches, rendering decades of research potentially obsolete.
Which choice completes the text with the most logical and precise word or phrase?
A. validates
B. preserves
C. reinforces
D. destabilizes✓ Correct
Detailed Answer Explanation
Choice D is the best answer. "Destabilizes" is correct because it means "makes unstable or uncertain." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: A ("Validates" means "confirms," which doesn't fit the context.), B ("Preserves" means "maintains," which doesn't fit the context.), C ("Reinforces" means "strengthens," which doesn't fit the context.).
